Mechanical Pressure Gauges

SIKA pressure gauges are quality measuring instruments for use in industrial applications. They are fitted with stainless steel

cases as standard and comply with the EN 837-1 until EN 837-3 European standards.

SIKA offers various models based on three different measuring elements: bourdon tubes, diaphragms and capsule elements. All

three types operate on the same principle: elastic deformation of the measuring element under the influence of pressure. This

motion is coupled to a pointer mechanism. The appropriate type (bourdon tube, diaphragm or capsule element) for a particular

application depends on the application area, necessary display range and installation location.

Bourdon tube pressure gauges

Bourdon tube pressure gauges are the most common type in

many areas and are used to measure medium to high pressures.

They cover measuring spans from 600 mbar to 4000 bar.

The measuring element is a curved tube with a circular, spiral

or coiled shape, commonly called a bourdon tube. This tube

moves outward when the pressure inside the tube is higher

than the external pressure, and inward when the internal

pressure is lower. This motion is proportional to the pressure to

be measured, and it is coupled to the pointer mechanism.

General information

The provisions of Part 2 of the EN 837 standard should generally

be observed when selecting pressure gauges. We offer a variety

of standard and special versions of pressure gauges, as well

as matching accessories. On request, we can fit our gauges

with electrical limit switches, which are described in a separate

section limit switches. Please don‘t hesitate to contact us if you

have any questions.

Capsule element pressure gauge

Capsule element pressure gauges are used to measure air

and dry gases at low pressures. They cover measuring spans

from 2.5 mbar to 600 mbar. The measuring element consists of

two metal diaphragms soldered together to form a cylindrical

bellows chamber. This capsule element expands when the

pressure inside the element is higher than the external

pressure, and it contracts when the internal pressure is lower.

This motion is proportional to the pressure to be measured, and

it is coupled to the pointer mechanism.

Diaphragm pressure gauges

Diaphragm pressure gauges are used to measure gases and

liquids. They cover measuring spans from 10 mbar to 40 bar.

The measuring element consists of one circular diaphragm

clamped between a pair of flanges. The positive or negative

pressure acting on these diaphragms causes deformation of

the measuring element. The magnitude of the deformation is

proportional to the pressure to be measured, and it is coupled

to the pointer mechanism.

218

Case type

The stainless steel case is available in two versions: with a

bayonet ring (type MRE) or with a crimped-on ring (type MRE-g).

Case ventilation is provided by a pressure equalisation insert.

Display ranges

DIN display ranges from -1...0 bar to 0...1000 bar are available

(max. 600 bar with brass connection or 1000 bar with stainless

steel connection). Gauges with special ranges can be provided

on request.

Degree of protection according to EN 60529

SIKA manometers with 63 or 100 mm stainless steel cases in

marine design are high-quality manometers that we produce

in common versions and in large quantities. We keep these

versions in stock specifically for shipbuilding and the shipping

trade. By concentrating on optimised quantities of common

types we achieve attractive sales prices.

These devices are only available as described in the data

sheet. We implement options and special wishes based on our

industrial versions (types MRE and MRE-G).

Type Mreg-KWe manufacture pressure gauges specifically designed for use

in refrigeration and chiller systems and specifically adapted to

this application. They have scales showing both the pressure

and the pressure-dependent evaporation temperature of the

corresponding refrigerant. Some of these pressure gauges

also have additional safety features according to the hazard

classification of the refrigerant.

• Stainless steel crimped ring case

• Bottom or rear connection

• Brass connection (stainless steel for R717)

• EN 837-1 accuracy class 1 (class 1.6 with 63 mm case)

• Standard display ranges -1 to 15 bar, -1 to 24 bar,

-1 to 30 bar

• Standard refrigerants R134a, R404a, R407c, R507, R717

Designed and built for safety

Refrigerants are classified into three groups according to

VBG 20 Sect. 3:

• Group 1:

Non-flammable refrigerants with no harmful impact

on health

• Group 2:

Toxic or corrosive refrigerants and refrigerants with a lower

explosion limit of at least 3.5 % by volume when mixed with

air

• Group 3:

As group 2, but with an explosion limit below 3.5% by

volume

SIKA refrigeration pressure gauges comply with EN 837-1

safety level S2 for refrigerants in groups 1 and 2 and EN 837-1

safety level S3 for refrigerants in group 3.

Bourdon tube pressure gauges, chiller version

Type MREG-K, nominal sizes 63, 80 and 100 mm

Option

Thread 7/16“-20 UNF with tapered seal according to DIN 3866

for solderless connection to 6 mm tubing (¼“ flare)

The provisions of the EN 837-2 standard should be

observed when using pressure gauges.

247

Scales

Our gauges are available with standard display ranges of -1...15 bar, -1...24 bar and -1...30 bar. The scale plates are printed with

combined pressure and temperature scales. The pressure scales are in bar, kPa / MPa or psi; the temperature scales are in °C

or °F and match the evaporation pressure curve of the corresponding refrigerant. In accordance with DIN 16112, the temperature

scales are implemented as „dot scales“ and are usually printed in colour. Gauges with scales for more than one refrigerant can

be supplied on request. SIKA offers a wide variety of ready-made special scales for individual measuring ranges and refrigerants.

Please contact us to discuss your needs.


All pressure gauges have standard G¼ B or G½ B thread

(also available with NPT thread). As an option, we can supply

pressure gauges with ¼“ flare connection according to the

diagram. The components in contact with the medium being

measured are made from brass or bronze. Non-ferrous metals

are not allowed in gauges for use with ammonia refrigerant

(R717, NH3), so stainless steel alloys are used for this purpose.

Scales and types

Examples of DIN 16112 compliant scales for R22 and R407c

Case

Cases of refrigeration pressure gauges can be painted in colour

on request to enable the gauges to be visually associated with

the corresponding cooling circuits and allow the system to be

laid out for easier comprehension. For example, red may be

used for the high-pressure side and blue for the low-pressure

side.

Construction

The instruments are provided with two independently working

measuring systems, each system with its own pressure

connection. The connections are marked with + and - (+ for

the higher pressure, - for the lower pressure). A special duplex

movement with the pointer arbors seated co-axial into each

other transfers the pressure proportional motions of both

Bourdon tubes to the pointers.

SIKA differential pressure gauges with two bourdon

tubes are instruments for measuring two different

pressures and indication of the differential pressure.

They are provided with turnable scale disc bar / mWS

for direct indication of the positive or negative differential

pressure (each 50 % of the full scale value). They are used in

heating systems (supply and return lines) and filter systems.

Differential pressure gauges should be selected with a full-

scale value that is at least as large as the maximum pressure

occurring in the system. The pressure gauges can be operated

at pressures up to the maximum scale pressure, but they

cannot withstand overpressure. To ensure good readability of

the differential pressure, the differential pressure should not be

less than about 20 % of the full scale value.

Diaphragm pressure gauges, safety version

Type MPE-S, nominal sizes 100 and 160 mm

Pressure gauges with horizontal diaphragm allow to find suitable versions for even difficult kinds of media, such as aggressive, contaminated or viscous media. The stainless steel

bayonet ring case is designed for applications where a rust

resistant, sealed case of high chemical resistance is required

(dirty damp, or corrosive atmosphere). The gauges conform to

safety class S3 requirements as specified in EN 873-1.

• Pressure gauges compliant with EN 837-3 S3


• Stainless steel connection, G½ B

• Connections at bottom, with enlarged channel opening

in case of PTFE lining, optional open flange

• EN 837-3 accuracy, class 1.6 (class 2.5 with protection foil,

filled and vacuum ranges))




Overload Up to 5-times, max. 40 bar and max. 2.5 bar for flange Ø 160 mm
